CRITICAL

9.1

Description

A broken access control vulnerability exists in Serv-U which when exploited, gives a malicious actor the ability to create a system admin user and execute arbitrary code as a privileged account via domain admin or group admin privileges. This issue requires administrative privileges to abuse. On Windows deployments, the risk is scored as a medium because services frequently run under less-privileged service accounts by default.
